This is a dotey wee cardigan & it knit up in a flash. I knit the largest size (intended for a newborn) & it seems tiny. I would normally knit at least 3 − 6 months for babies, but the mother-to-be really liked this one.
It'll hopefully fit the child long enough for a photo!

A very simple pattern; knit a tube of ribbing & then bind it closed at the top & adorn with button/toggle/beads of your choice. It's very stretchy so I think it will last the wee ones for a while as they grow. I used just under a ball for each hat so it's be a great way of using up those odd balls of aran weight yarn.

I've now knit this pattern 4 times; enough!! For these two cardigans, I sewed the sleeves & body together before knitting on the collar. My recently learned mattress stitch skills meant the original knit-on collar would not sit right.
